This paper presents a blind digital video watermarking scheme, which is especially robust to camcorder recording attacks and also to a variety of common video processing and geometric distortions. Using the fact that nearby frames of a video sequence are quite similar, the method embeds the watermark by temporal modulation of the frames. The watermark(More)
This paper proposes a new approach to motion vector field smoothing for block-based motion-compensated frame interpolation (MCFI). Based on the assumption that an observed motion vector field, which is the result of a block-based motion estimation (BME), is a degraded version of the true motion vector field, we calculate the maximum a posteriori (MAP)(More)
